Reddit mentions of Faucet Queen Zip-It Drain Clog Tool

Drain Zips. I have a few of these and they work great -- along the same lines as your wire hangar, but probably better reach and grab. You can find them at any local hardware or big box store for just a few bucks.

If it's a deep, full clog, I've got one of these that also works like a champ, but you need a garden hose to supply force: http://www.amazon.com/G-T-Water-Products-186-Attachment/dp/B0000CBIWC/ref=sr_1_1?ie=UTF8&qid=1422409317&sr=8-1&keywords=drain+pressure+hose

Probably $10-$20 also at any hardware or big box store.
